INSTALLATION OF WOODY DEBRIS, BERMS, POOLS AND GLIDEs

tat restoration 100The River Tat is a tributary of the River Wensum and forms part of the River Wensum Site of Special Scientific Interest. The planform and channel geometry has historically been subjected to significant modification including diversions, straightening, widening and the construction of an online lake system.

The aim of the restoration work was to ‘kick start’ natural morphological processes throughout the reach.

A key restoration measure has been the installation of Large Woody Debris (LWD). Reducing tree cover in heavily shaded areas, by selective coppicing, provides a sustainable source of material. This also allows light onto the river, promoting marginal vegetation to establish. LWD has introduced flow diversity, helping keep the gravels free from silt and providing overhead cover for fish.
